first embodiment

[0024]the present invention will be described in detail below.

[0025]With reference to FIG. 1, a biometric characteristic data imaging apparatus of the present exemplary embodiment (hereinafter referred to as “imaging apparatus”) will be explained. Imaging apparatus 100 is provided with imaging unit 104 such as a camera or the like provided within imaging apparatus 100. Imaging apparatus 100 includes fingertip guide unit 102 and finger root guide unit 103 for guiding an imaging area of a fingerprint and / or a finger blood vessels pattern to the suitable location for imaging. Moreover, imaging apparatus 100 also includes a palm guide unit 101 for guiding a palm to the location suitable for imaging of a palmar print and / or a palm blood vessels pattern. These guide units are provided at an upper part of imaging apparatus 100.

[0026]Here, a fingertip of a user is placed on fingertip guide unit 102 and a finger root of the same finger on finger root guide unit 103 for the imaging of a finge...

second embodiment

[0075]the present invention will be described in detail below.

[0076]Here, the same reference numerals as that in the first exemplary embodiment represent the same structural elements.

[0077]The second exemplary embodiment has almost the identical structure in the system structure to that of the first exemplary embodiment explained above (FIG. 1) and is further provided with diffuser 502, focusing lens 503, and infrared light transparent filter 504. Therefore, biometric characteristic data of fingerprint and blood vessels pattern of the finger and palmar print and blood vessels pattern of the palm can be imaged in higher image quality with imaging unit 104.

[0078]First, in this exemplary embodiment, focusing lens 503 is provided at the upper part of the lighting unit 208 for fingerprint and palmar print as shown in FIG. 6(A) and FIG. 6(B). Accordingly, the light radiated to the guided finger or palm from the lighting unit 2 for fingerprint and palmar print can be polarized to almost th...

Abstract

The imaging apparatus for recognizing an image of the present invention determines for recognition a user by imaging a recognition pattern of a palm or a finger. The imaging apparatus for recognizing an image comprising a palm guide unit for guiding an imaging area of a palm, a finger guide unit for guiding an imaging area of a finger, and an imaging unit for imaging biometric data of the imaging areas of the palm and finger.

Description

[0001]This application is based upon and claims the benefit of priority from Japanese patent application No. 2008-010999, filed on Jan. 21, 2008, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to an imaging apparatus for recognizing an image for determining a user on the basis of biometric characteristic data collected by imaging a hand.[0003]In the biometric characteristic data authenticating technology for recognizing a user by extracting an image of a finger, a system has been introduced to match a pattern of the finger skin such as a fingerprint or a blood vessels pattern against the previously-stored data. Moreover, even in the biometric data authenticating technology for recognizing a user using a palm image, a system is also proposed to match a pattern on the skin surface such as a palmar print or a blood vessels pattern of a palm against the previously-stored data. For example, for an...
